Since October 5, doctors in Shetland, Scotland have been authorized to prescribe nature to their patients. It's thought to be the first program of its kind in the U.K., and seeks to reduce blood pressure, anxiety, and increase happiness for those with diabetes, a mental illness, stress, heart disease, and more.

There is a whole leaflet of nature prescription suggestions that accompanies the program, filled with amusing, charming, sometimes seemingly off-kilter suggestions: in February, you can make a windsock from a hoop and material to "appreciate the speed of the wind"; in March, you can make beach art from natural materials or "borrow a dog and take it for a walk"; in April, you can "touch the sea" and "make a bug hotel"; in May, you can "bury your face in the grass"; in July, you can "pick two different kinds of grass and really look at them"; in August, you can summon a worm out of the ground without digging or using water; in September, you can help clean the beach and prepare a meal outdoors; in October, you can "appreciate a cloud"; you can "talk to a pony" in November, "feed the birds in your garden" in December, and do so much more. All on doctor's orders.

In Landmarks, the writer Robert Macfarlane bemoaned the disconnect between the landscape and the words used to describe and engage with that landscape, as well as all that disconnect implied. The book attempted to serve as something of a catch-all for words Macfarlane worried were being lost. There are Shetlandic words in the book, including grumma (mirage caused by mist or haze rising from the ground), flaa (hunk of turf, matted with roots of heather and grass, torn up by hand without a spade and used in thatching), skumpi (clumsy, lumpish peat; outermost peat in each row as the peats are cut out of the bank), dub (very deep bog or mire), yarf (swamp), iset(color of ice: isetgrey, isetblue), and others.

One could imagine that someone encouraged to spend more time in nature by their doctor won't just feel better—they might think about tearing a flaaout of some skumpi before turning around and heading back home. They'll spot some isetgrey ice. And, as they reconnect with nature, they will reconnect with the language of nature, a language that is frequently site-specific and carries with it a quiet institutional memory of its own, a memory worth recalling as the world faces development, urbanization, and climate change.
